for loop not working in windows .bat file

Question

I need a windows batch-file which will be placed in the server path. My data files are placed in another path.

1. Once I run the bat file, it should search the list of files in the given path, (could be in same path where bat file placed).
2. It should search for forward slash / , back slash \ , special characters and replace with the SPACE

sample Original file

Corrected file

I used below code:- it work for single file. When I open loop it is not working. Please help.

and also file which ends with *.err should NOT be picked from this loop.

Give a try and tell me if this work or not on your side:

I added a newline to backup your dump folder and its contents if something went wrong!

@Karun I think you better try for some bash script instead of bat.

You can use SED Stream Editor to search and replace characters from file.

Example:

sed -i 's#\\##g' sample.txt # This will replace back slash from sample.txt
sed -i 's#/##g' sample.txt # This will replace forward slash from sample.txt

To execute for multiple files in a directory, you can use for loop as well. Save all your string replacement commands to a bash script like test.sh and execute it using for loop.

Example:

sed -i 's#\\##g' $1
sed -i 's#/##g' $1

Add above lines in test.sh and run below line of script.

for file in $(ls -l /home/abc/*.txt | awk '{print $NF}'); do bash test.sh $file; done
